Improving Clinical Decision Support through Interpretable Machine Learning and Error Handling in Electronic Health Records
Mehak Arora, Hassan Mortagy, Nathan Dwarshuis +5
The objective of this work is to develop an Electronic Medical Record (EMR) data processing tool that confers clinical context to Machine Learning (ML) algorithms for error handlin…
Reusing Combinatorial Structure: Faster Iterative Projections over Submodular Base Polytopes
Jai Moondra, Hassan Mortagy, Swati Gupta
Optimization algorithms such as projected Newton's method, FISTA, mirror descent, and its variants enjoy near-optimal regret bounds and convergence rates, but suffer from a computa…
Walking in the Shadow: A New Perspective on Descent Directions for Constrained Minimization
Hassan Mortagy, Swati Gupta, Sebastian Pokutta
Descent directions such as movement towards Descent directions, including movement towards Frank-Wolfe vertices, away-steps, in-face away-steps and pairwise directions, have been a…
Electrical Flows over Spanning Trees
Swati Gupta, Ali Khodabakhsh, Hassan Mortagy +1
The network reconfiguration problem seeks to find a rooted tree such that the energy of the (unique) feasible electrical flow over is minimized. The tree requirement on the…
